I I SHOE-TREE.

To all whom it may concern:

Be it known'that I, J oHn DANIEL DUN- FIELD, of the town of Petrolia, in the county of Lambton, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Shoe-Trees, of which the following is the specification.

My invention relates to improvements in shoe trees and'the object of the invention is to devise a metal tree which is readily adjustable to suit various sizes ofshoes and which may be easily and quickly placed in or removed from the shoe and it consistsessentially of the following arrangement and construction of parts as herein after more particularly explained. Figure 1 is a longitudinal sectional View through the shoe and my device in position therein.

Fig. 2, is adetail view of the strut-members connecting the toe and heelpieces of 3 the tree.

Fig. 3, 1s an enlarged sectlonal vlew 1n l1ne my 1n Flg. 2.

Figs. 4: and 5 are fragmentary detail views;

illustrating the connection between the strut members.

Fig. 6 is a detail view ofthe key for securing the strut membersin the adj acent position. r y

In drawings like characters of reference indicate the corresponding parts in'the various figures. I

1 indicates a shoe. 2 is the metal toe piece of my shoe tree provided with an internal 7 depending lug 3. is theheel piece provided with an internal inwardly extending lug 5. Atoe piece 2 fits in the shoe and a heel piece 4 in the heel of the shoe in the usual manner common to various classes of shoe trees. I will now describe the strut connection for connecting the toe and heel pieces together and which forms the subject matter of the applicants invention. 6 is a bar which is pivotally connected at one end to the lug 5 by a pin 7 and provided at its.v

opposite end with a hole Shaving a rectangular notch 9 cut in the edge of the hole. 10 is a sheet metal bar which is for'med in inverted U form, the lower edges of the depending arms of the U being turned inward on themselves at 11 and 12, as shown in Fig.

3 so as to form edges 18 and 14 extending longitudinally of the bar 10. 15 are series of orifices formed in each arm of the U, each.

orifice corresponding'in form to the orifice 8 and each so placed in the bar 10 as to be brought successively into a line with thejorifice 8 when the bar 6 ismo'ved longitudi nally within-the bar 10. The back is provided in one edge with outwardlystamped portions 16 and 17 which rest upon the ledges Band 14 and are slidablethereon. Theend edges of the depending arms of the U bar 10 i V are turned inward at;18 and19 so as to engagewith. the portions 16 and 17 to prevent the bar 6 being drawn from the bar 10. The 1 end of the bar 10 adjacent to the toe piece 2 is pivotally connected by a pin 20 to the lug 8. 21 is a key the shank of which. fits the orifices 15 and 8, The key 20 is provided with alug 22 extending. from the shank and I which is adapted to passthrough the notch 9 of the orifices 8 and 15 when inserting the key. through the orifices 8 and 15. The bars gether, the lug 22 being turned out of alinement with the notches 9 soas to prevent its withdrawal. When the shoe tree is inserted in the shoe the bars 6 and 10 are drawnup 7 5 '6 and 10 are thus pivotally connected tothe dotted lines in Fig. 1. 'When the toe and. heel pieces are inserted in the shoe the bars 6 and 10 are forced into an ,alined position, the downward movement being limited by the edge of the bar 6 engaging the base portion of the invertedU bar 10. When withdraw-. ing the'tree the reverse of this operation takes place. If the shoe tree is to be usedin a larger or smaller shoe all that is necessary to do is to withdraw the key from the ori fices 8 and 15 and thenmove the bar 6 longitudinally within the bar 10 so as to carrythe orifice 8 into alinement with another'of the f "I orifices 15 of the bar 10; the key isthen rein;- serted.

By this description it will be seen that have devised a very simple form ofshoe treewhich may be readily adjusted to suit any size of shoe and which is easily withdraw able from and shoe; I

What I 'clalm as my lnventlon 1s:

10o 1 placed in position within the 1. In a shoe tree, the combination with a so Ward into the angular position indicated by 2 p i 'n I W 1,353,327

, inturned edges providing spaced track, surfaces vv1th1n the member, a second bar member pivotally connected to the heel piece slidf 1 ing Within said first member and provided vwith I projections supported on said track surfaces, and means for pivotally connect ing the bar members together. I

2. A device according to claim 1 in which 10 the free end of the first mentioned bar mem berhasopposite side portions thereof directed inwardly to engagethe sides of the second bar member and thereby cooperate With theprojectionson the latter to prevent 15 comp1ete separation of'the'bar members.
